    Collision/reaction cell ICP-MS with shielded torch and sector field ICP-MS for the simultaneous determination of selenium isotopes in biological matrices حسب Al-Saad, Khalid A.

    منشور في 2011
    "…The determinations of selenium isotopes in biological samples were performed using both inductively coupled plasma collision/reaction cell quadruple mass spectrometer (CRC-ICP-QMS) and inductively coupled plasma sector field mass spectrometers (SF-ICP-MS). To significantly decrease the argon-based interferences at m/z 74 (36Ar38Ar), 76 ( 38Ar38Ar, 40Ar36Ar), 78 ( 38Ar40Ar), and 80 (40Ar40Ar), the gas-flow rates of a helium and hydrogen mixture used in the collision cell were optimized to 1.0 mL/min H2 and 3.5 mL/min He. …"

    Impact of combined oil-in-water emulsions and particulate suspensions on ceramic membrane fouling and permeability recovery حسب Abdalla M.

    منشور في 2019
    "…The addition of 1500 mg·L−1 of bentonite to a 10 vol.% emulsion resulted in a permeability decrease of 3.5–5 times over that recorded for the emulsion, and 8–36 times lower than that of the bentonite suspension. …"
